With some product categories there are independent testing laboratories that do a fairly good job of determining quality. The automotive industry comes to mind.

It seems it's a revealed preference that most people really don't care that much about quality, or there would exist a host of companies like Consumer Reports to meet the demand. Complaining on social media about enshittification and evil corporations does not put skin in the game.

I myself constantly complain about the atrocious quality of most consumer software products, but I'm not sure how much I'd be willing to pay for a subscription to an independent testing report.
